lang/asis: Fix build on gcc5-aux

The OpenVMS support was removed on gcc5's GNAT so the GPL 2014 version
of ASIS won't build unless the references to OpenVMS are removed.  Rather
than use EXTRA_PATCHES, just remove them unconditionally.  This doesn't
cause any issue for gcc-aux-built ASIS and the ports that use it.
